My friend has a laptop running WinXp pro and when he started up the computer, the screen lights up but nothing shows up. Only weired colors shows, and I think the screen is burned or defected somehow. The laptop has an adapter that connects to a regular monitor, so I hooked it up and then startup the computer. On the monitor everything was fine but not on the laptop screen. After when the computer did a system check, the monitor screen went blank. After that nothing shows up.
Could it be a hardware problem or software problem?
